Automatically pre-programs and erases the chip or any sector
• Embedded Program™ Algorithms
Automatically writes and verifies data at specified address
•Data Polling and Toggle Bit feature for detection of program or erase cycle completion
•Low VCC write inhibit £ 3.2 V
• Sector protection
Hardware method disables any combination of sectors from write or erase operations
• Erase Suspend/Resume
Suspends the erase operation to allow a read data in another sector within the same device
